Things I’ve built

Mostly ideas from class, or from games I play, that I wanted to try for real. Each one runs right here on the site.

FeaturedWork · Simulation Fruit Fly Dispatcher I took a fruit fly’s navigation circuit, wired neuron by neuron from the FlyWire connectome, and let it run a week of fresh-food deliveries against Google’s OR-Tools. Each brain gets four levels of information, from a fly that finds stores by smell alone up to live company data. I wanted to see what matters more for getting food where it needs to go: who makes the decisions, or what they know. 55 stores · 7 days · 4 brains × 4 levels of knowledge · 300+ simulated weeks
